DH-300K Gold Testing Machine, Gold karat Meter Price Jewellery Testing Machine
Applicationpawn broking, bank, jewelry shop, precious-metals recovery, jewelry factory, Gemstone Testing Center,precious metals researching.etc.
In accordance with archimedes principle water buoyancy method, GB/T1423 of precious metals testing standard,and so on.
Combine archimedes principle with micro electronic technique;adopt sensor imported from Germany,the purity can be calculated through measuring density of precious metals.features of no damage on sample;simple operation,fast and accurate.
K value of gold,PT value of platinum,density value,purity percentage can be measured.
Specifications
Model:DH-300K
Density resolution: 0.001 g/cm3
Maximum weight:300g
Minimum weight:0.005g
Measurement time:15s
Features
a)The purity of gold,platinum,and other precious metals can be measured in a short time.the fake can be distinguished.
b)No damage testing, cleaning and environmental protection.
c)Measuring just need 15 seconds,convenience,stabilization,and accuracy.
d)Multi-mode,gold mode,platinum mode,other precious metals mode can be shifted.
e)Multi-function;the purity of other precious metals can be measured.such as tin,copper,silver.,etc.also can be used as precision balance.
f)Function of top and bottom limitation;it can display"OK,HI,LO" in the state of qualified,exceed,less;Prompt alarm.
g)Function of automatic zero tracking,buzzer warning,and overload warning.
h)Function of solution compensation.necessary if liquid other than water is used as a medium for measurement.
i)Adopt the completed high-capacity transparent injection mould sink,which can resist damage and corrosion.
j)Adopt the completed special windproof and dustproof cover,which is convenient and durable.
k)Interface of RS-232C is included.the machine is available to connect PC with printer.
Measurement Procedure
a)Measure the gold weight in air,and then press the ENTER button to memory.
b)Place the gold into water to measure the weight,and then press the ENTER button to memory.show the K value of gold,purity percent,density value.
